operated to rotate the jaws and end supports'lc so that a coil of the sha e shown in Fig. 6 and indicated by dotted ines in Fig. 2, is formed, the head being rotated until a sufiicient number of turns is laid within the said jaws. slightly to allow the arms 7', to be rotated about the ivots j to the osition shown in Fig. 4;. T is is effected y the operator, who, By ulling the handle n in the direction indicated by the arrow in Fig. 1, slides the blockf and with it the jaws I) along the" guide-rods 9' so as to open out the coil to the shapp shown in Fig. 7 and indicated by dotted 'nes in Fig. 4. In moving to this position the end supports is may turn freely-upon their pivots Te though in some-cases they to give them a positive movement from the 2D may be attached to a parallel motion so as osition shown in Fig 3 to that in Fig. 4; I

.iave found, however, that this is not usually necessary. To remove the coil from the machine the wing-nuts la are slightly unscrewed so as to release the cheeks 70 which can then be removed from the screws 7:" The coil is then withdrawn from the jaws a, a and can be readily passed over and ment of the l away from the screws k in the directionof their length.

The movement of the block f is limited by a stop 0 which can be set at any desired point along the rods 9', g by means of set screws 0 r A screw p is preferably providedin the rotatable head cl and can be screwed in or out for the purpose of limiting the moveock'fin the direction opposite to that indicated by the arrow in Fig. 1 so that the jaws a may be set in line with the jaws b and end supports 70.

I wish it to be understood that the constructio'n described above is by no means necessary to the carrzying out of my invention. Also, where a large number of coils of the same size have to be turned out, a machine 45' can be made adapted to the particular size of coils without the adjustments which are nec essary where coils o varying sizes have to be made.

it is obvious that in some cases instead of rotatin the device upon a mandrel, it mightbe fine and the wire mi htbe wound 'on the jaws by carrying 'roun Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be per formed, I declare that what I claim is 1.. In an armature 'coil winding machine, the combination comprising the upper and The nuts j are then unscrewed of jaws rigidly secured thereto, a

the bobbin from 5 lower sets of jaws and the end supports car- --ried by pivoted levers, suitably mounted so as to enable a plane coil to be wound and then shifted to open out the coil, substan-.

tiafly as described. v

2. In an armature winding machine, the combination with a rigidly secured upper set of jaws, of a lower'set of jaws, guides on which said lower set of jaws are mounted, said lower set of jaws being movable on said guides into and out of the plane of the upper j aws-and the movably mounted end supports, substantially as described.

' l 3. In an armature winding machinefthe combination with a revoluble head, of a pair of jaws rigidly mounted thereon, a air of movable (jaws, guides forsaid movab e jaws connecte supported from said head and movable in relation thereto, substantially as described.

I 4. In an armature winding machine, the

, combination with a revoluble head, of a pair of jaws rigidly secured thereto, a air of movable aws, guides for said movab e jaws, and end supports mounted upon levers,

adapted to be secured in rigid relation to said head, substantially as described.

' 5. In an armature winding machine, the.

combination with a revoluble head, of a pair of jaws rigidly'sec'ured thereto, a air of movab e aws, guides for said mova'le aws se cure to said head, lever supports pivoted to to said head, and end supports.

a rigid part of the machine, means whereby,

said levers may be rigidly secured in position or released to permit movement of the same,

7'. In an armature coil winding machine, the combination comprising the head 11 on whichare mounted the jaws a a, the levers '7 j carrying the end supports, and the block carrying the jaws b b, so. as to enable the coil to be opened after it is wound, substantially as described.
